During the Cold War the U.S. built a secret facility to gather intelligence on East Germany. That facility still exists.

On the second-highest hill in Berlin sits the carved-out remnants of Field Station Berlin Teufelsberg, a former NSA spy station used to collect signals intelligence on Soviet-aligned East Germany during the Cold War. Before the aging structure decays beyond repair, a newly appointed manager hopes to give a second life to this architectural relic from a very different, yet not-too-distant, time. Can it be saved? We went inside the graffitied and hollowed out building to get a sense of its future.
